Yosemite San Francisco Font

Replace Helvetica Neue on your 10.10 Yosemite Mac with San Francisco – the Watch font.

The font is adapted from San Francisco Display – Apple’s new typeface for the Apple Watch. This project was inspired by jenskutilek’s Fira System Font Replacement. The fonts were generated using dtinth's Yosemite System Font Patcher.

How to Install:

  1. Download the zipped font files.
  2. Copy the 5 font files to /Library/Fonts on your Mac. (protip: press cmd+shift+g while in Finder to type the path directly.)
  3. Run sudo chown root:wheel /Library/Fonts/System\ San\ Francisco\ Display* to set the proper ownership of the font files.
  4. Repair Disk Permissions diskutil repairPermissions / (for good measure)
  5. Log out and log back in to apply the changes.

How to Uninstall:

  1. Navigate to /Library/Fonts on your Mac and delete the 5 files starting with System San Francisco Display.
  2. Log out and log back in to apply the changes.

How does it Work?

These San Francisco fonts have a special name table with names identical to those of the system fonts. Because the font folder /Library/Fonts takes precedence over the fonts which are in /System/Library/Fonts, these specially crafted fonts are used for the user interface instead of the real system fonts. The original system fonts are not deleted or modified in any way.

I assume no copyright over these fonts, nor any liability for improper installation or improper use. Use of these fonts should conform to Apple’s express copyright and rules.
